I studied biology at the Free University of Berlin and received my doctorate in 2004 with a focus on zoology. My own research focuses on acarology, entomology, phoresy, evolutionary biology, ecology and taxonomy. Between 2004 and 2014 I held courses with lectures at the FU Berlin and published more than 25 scientific articles. I have also worked on TV documentaries as a macro filmmaker and publish videos on my YouTube channel. I present photo projects on the Adobe Behance page https://www.behance.net/stefanwirth?locale=de_DE
I publish science communication articles on various of my channels.

The cold tolerance of an adult winter-active stonefly: How Allocapnia pygmaea (Plecoptera: Capniidae) avoids freezing in Nova Scotian winters
The authors Jona Lopez Pedersen and team meanwhile published their 2025 preprint in the peer-reviewed journal The Canadian Entomologist in January 2026. This laboratory study is the first to comprehensively investigate fundamental aspects of cold tolerance and freeze avoidance in the winter-active stonefly Allocapnia pygmaea (Plecoptera, Neoptera). Compared to their preprint, the researchers have refined only…

Loss of a morph is associated with asymmetric character release in a radiation of woodland salamanders
This preprint about the evolutionary influences of polymorphisms in North American woodland salamanders by B. Waldron et al. (2025) has now been published in the peer-reviewed journal Evolution. The study examines the directions in which the morphological forms – striped, unstriped, and polymorphic – evolved and the respective rates of evolution. The authors found that…
